icarter,
As a Captain on Citation Jet 2+ my day rate was 400 Euro's plus 50 per diem. As Kelly says in better times, with a good owner / operation / ac type, the rates can be very rewarding indeed.
Times are very hard at present in Business Aviation. Across all types, there is a huge excess of hugely experienced drivers.
Insurance requirements tend to be very high as compared with 'the airlines'. The owners have very specific requirements regarding hours, type experience, age, languages - the list goes on!
I cannot see this situation improving any time soon.
The truth is; there are no paid flying jobs in any part of the aviation industry at the moment for any wannabe.
